We live seeing, touching, or throwing on considerable textile in our life consciously and unconsciously. Since a Korean-style house is a dwelling space in life style of sitting on the floor with ondol(Korean floor heater), use of textile is limited to bedding goods. However, as western life style takes firm root, use of textile for interior design is increasing. As well, as apartments and foreign style houses have gotten lodgment since 1980, life style is being changed rapidly. So, textile became required factors in dining space where little textile existed. Through literature, history of textile is considered and design image concept is created based on the consideration. In addition, the created concept can be applied to various textile design, which can be a good tool to express eating culture of the country as well as the country's image.

Even in moderate to low seismic regions like Korean peninsular where wind loading usually governs the structural design of a tall building, the probable structural impact of the design basis earthquake or the maximum credible earthquake on the selected structural system should be considered at least in finalizing the design. In this study, by using response spectrum analysis and time history analysis method, seismic performance evaluation was conducted for wind-designed concentrically braced steel highrise buildings. Input ensemble was normalized to be compatible with expected peak ground acceleration. The analysis results showed that wind-designed concentrically braced steel highrise buildings possess significantly increased elastic seismic capacity due to the system overstrength resulting from the wind-serviceability criterion and the width-to-thickness ratio limits on steel members. The time history analysis tended to significantly underestimated the seismic response as compared to response spectrum analysis. Further detailed studies regarding selection and scaling scheme of input ground motions is needed.

The problem of separation between the teaching and the practice of architectural design in Korean universities has activated this study. Comparison between two professor-architects in Italy through their various activities has been made during the period of 1991-1992 in the Istituto Universitario di Architettura di Venezia. The names of the two professor-architects are Aldo Rossi and Franco Mancuso. Their teaching activities in their architectural design class with their assistants, their background and formation of architectural theory, and two realized (and prized) works of them have been compared. The results show that there is a great difference (or oppositions) in their world-view and their attitudes towards architecture, the one as an empiricist, the other as a rationalist. But the most impressive observation must be the fact that all of them were coherent in their teaching, theory and practice, although this raises another qustion about the 'rationality' in architecture.

Feature-based modeling and history-based modeling are the two main paradigms that are used in most of current CAD systems. Although these modeling paradigms make it easier for designers to create solid model, it may pose dependency constraints on features that are interacting one with another. When editing such features, these constraints often cause unpredictable and unacceptable results. For example, when a parent feature is deleted, the child features of the parent feature are also deleted. This entails re-generations of the deleted features, which requires additional modeling time. In order to complement this situation, we propose a method to delete only the features of interest by disconnecting the dependency constraints. This method can provide designers with more efficient way of model modification.

This paper describes the design and implementation of Korean History Web courseware using semantic network in order to build learning environment in the viewpoint of cognitive flexibility theory. The most important thing in design for a courseware using semantic network is to build learning environment. The first step to do this is to analyze learning contents and after that we should define the type of link between learning subjects. We should develope the knowledge map which has the link of each type connected with every learning subject.

The chairs are one of the most important furniture in this modern society, as we know that history of furniture is made of history of the chairs. Among the chairs, the stool, which made by only sit and legs, forms the basis of the chairs. The stool plays an important part in the human body to support and also help to make an agile movement In a short period of time. The stool is the minimum unit of chair, which made of least size and simple structure; therefore it fits to study basic knowledge of furniture making. For that reason, we can see occasionally the schools of furniture design departments have chosen the stool making course in their foundation students' studio classes. However, the professional study on the stool, such as the study on the posture for designing stool, has not been developed yet. This study presents basic Information of design for stool by analyzing various stools formatively.

By taking a cable-stayed-suspension hybrid bridge with main span of 1400 m as example, seismic response of the bridge under the horizontal and vertical seismic excitations is investigated numerically by response spectrum analysis and time history analysis, its seismic performance is discussed and compared to the cable-stayed bridge and suspension bridge with the same main span, and considering the aspect of seismic performance, the feasibility of using cable-stayed-suspension hybrid bridge in super long-span bridges is discussed. Under the horizontal seismic action, the effects of structural design parameters including the cable sag to span ratio, the suspension to span ratio, the side span length, the subsidiary piers in side spans, the girder supporting system and the deck form etc on the seismic performance of the bridge are investigated by response spectrum analysis, and the favorable values of these design parameters are proposed.

Some model building codes stipulate that the design displacement of a building can be computed using the elastic static analysis results multiplied by the deflection amplification factor, $C_d$. This approach for estimating the design displacement is essential and appealing in structural engineering practice when nonlinear response history analysis (NRHA) is not required. Furthermore, building codes stipulate the consideration of accidental torsion effects using accidental eccentricity, whether the buildings are symmetric-plan, or asymmetric-plan. In some model building codes, the accidental eccentricity is further amplified by the torsional amplification factor $A_x$ in order to minimize the discrepancy between statically and dynamically estimated responses. Therefore, this warrants exploration of the reliability of statically estimated design displacements in accordance with the building code requirements. This study uses the discrepancy curves as a way of assessing the reliability of the design displacement estimates resulting from the factors $C_d$ and $A_x$. The discrepancy curves show the exceedance probabilities of the differences between the statically estimated design displacements and NRHA results. The discrepancy curves of 3-story, 9-story, and 20-story example buildings are investigated in this study. The example buildings are steel special moment frames with frequency ratios equal to 0.7, 1.0, 1.3, and 1.6, as well as existing eccentricity ratios ranging from 0% to 30%.

In ancient times, architectural design was seen as a critical task in building technologies. Specifically, form, dimension and structural design are of significant. These aspects are associated with each other and to be emerged as a whole. Designing plan dimension was deemed to be the core of design technology due to its close relationship with module system. Thus, its evolution as well as development process typically represents and reflects the spirits and contents of design technologies in ancient China. In China, the materials regarding ancient architectural technology include Yingzaofashi(營造法式) of Song Dynasty and Gongchengzuofazeli(工程做法則例) of Qing Dynasty. They show many aspects concerning materials, structure, scale system and building. In Yingzaofashi, although the length of objects are decided by 'cai(材)' and 'fen(分)', there are no regulations on length, width and height of a building. However, in the construction of ancient buildings, the above mentioned basic scales are very important in both design and construction. The present paper attempts to discuss the significance, namely, the design principles of length, with and height of ancient chinese architecture.
